SAW-SET.

Specification of Letters Patent.

Patented Oct. 29, 1907.

Application filed June 26. 1907- Serial No. 380.917-

To all whom it may concern:

Be it known that I, JOEL M. HANCOCK, a citizen of the United States,residing at Magnolia, in the county of Columbia, State of Arkansas, haveinvented certain new and useful Improvements in Saw-Sets; and I dohereby declare the following to be a. full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains' to make and use the same. I

his invention relates to saw sets and has for its object to provide atool which may be used in the setting of saws of different gages.

Broadly stated the tool comprises a flat metal plate provided at one ofits ends with a tooth for setting the teeth of cross cut saws and at itsother end with a plurality of notches for engagement with the teeth' ofsmaller saws to be set.

One of the novel features of the invention resides in beveling that edgeof the plate in which the notches are formed in the direction of thedecrease in the size of the notches so that in reality, the notches forthe larger or thicker teeth are of greater width than the notchcs of thethin saws. Heretofore in tools of this class, where a plurality ofnotches are provided, the notches have been formed of different breadthsbut of the same length and in setting the teeth of thin saws it has beenfound impractical to rapidly set the teeth without at the same timeinterfering with adjacent teeth.

In the accompanying drawings, Figure .l is a view in elevation of thetool, Fig. 2 is an edge view thereof, and, Fig. 3 is an end view of thetool.

As shown in the drawings the tool is formed of a plate 5 which isbifurcated at one of its ends as at (i and has the opposing edges of itsfur-cations toothed or serrated as at 7 whereby the tool may be used asan alligator wrench if desired.

Formed integral with one of the fur-cations is a rightangularly-directcdsaw-setting tooth S, which is to be used in setting the teeth of across-cut saw. in using the tool for this purpose, the cross-cut saw islaid llat upon a stump or block and the tooth S is placed upon the sawtooth to beset and the bifurcation upon which the tooth 8 is formed isthen struck sharply with a hammer, resulting, of course, in the bendingor setting of the saw-tooth. Inorder that the tool may be employed forthe purpose of setting the teeth of smaller saws, the

l l 1 i l 1 plate 5 is cut to form an angularly extending shoulder 9 atits end opposite to its bifurcated end, an extension 10 however beingleft for a purpose which will be presently stated. The shouldered edge5) of the plate is beveled upon opposite sides as at'll, its resultantedge being broader adjacent the extension .10 than at the Outer edge ofthe tool body and a plurality of notches 12 are formed in the saidbeveled edge of the shoulder and these notches decrease in size as theyapproach the narrow end of the said edge, and by reason of the fact thatthe said edge is beveled and itself narrowed as it approaches its outerend, the notches decrease in length also in the order named. 'lhcsenotches are designed for the reception of the teeth of the saw to be setand it will be understood that the teeth of the smaller saws are engagedin the smaller sized notches and the teeth of the larger saws in thenotches of larger size. By reason of the fact that the notches decreasein length in the same order and that they decrease in width, the teethof an extremely small saw may be set readily and quickly without intcrfering or bending the adjacent teeth.

Engaged through the extension 10 is a set screw 13 which, as tho tool isrocked to bend the said tooth of a saw strikes the saw when the toothhas been bent to the proper degree and indicates to the operator thisfact, it being understood that the said set screw may be adjusted topermit of the teelh being set to a greater or less degree as may befound expedient. if desired the extreme cud of the extension 10 may bebeveled as at 14 to form a screw driver.

What is claimed, is-

A tool oi the class described comprising a flat body por lion said bodyportion being provided at one of its ends with :1 shoulder cut at anangle and beveled upon opposite sides, \vhcrcby its edge is decreased inwidth toward its outer end. there being :1 plurality of notches formedin the said beveled angular-1y cut edge of lhe shoulder, the notches ofthe series being decreased in width and length as they approach [he saidouter end of the said shoulder, an extension formed integral with thebody of the tool and 'projectiug beyond the said shoulder, and a setscrew ongagcd through the extension.

In testimony whereof, I ailix my signature, in presence of two witnessesJOEL M. HANCOCK.
